JOHN S. BRENNAN, OF MILWAUKEE, WISCONSIN.

OIL-BURNER.

Application led March 25, 1919.

To all whom it may concern.'

Be it known that I, JOHN S. BRENNAN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in OilBurners; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in oi] burner stoves, more par ticularly of the so-called wickless type shown in application for patent of Robert Perlick filed September 25, 1918, Serial No. 255,677 and comprising, with respect to each burner head, a non-combustible capillary member movable vertically to vary the amount of oil supplied therethrough in conjunction with a constant level source of oil supply, a burner drum being disposed above and normally movable with this capillary member, but separable therefrom to permit lighting of the burner.

It is in general the object of my invention to strengthen and otherwise im rove the structure and to increase the e ciency of devices of this character.

In the operation of lighting the burner, it is necessary to lower the same to procure a maximum impregnation of the capillary member of the burner head and a consequent free supply of oil. The burner drum has heretofore been raised and lowered manually to expose the burner head for lighting. It has been found that, in this manual operation of separating ,the drum from theburner head, there exists in practice a liability for the operator to. neglect raising the' burner head to burning position after ignition, thus maintaining` an excess sup ly of oil resulting in a smoky and unsatis actory operation, which reacts unfavorably on the general popularity of stoves of this character, despite the fact that it is due to the carelessness of the operator. g

Y It is therefore an important object of my invention to provide an arrangement where in the liability of careless and incomplete operation of the burner with respect to lighting the same is lessened, thus safeguarding the operation of the stove, and itis more particularly -my object to *rovide an arrangement for automatica] y procuring a spaced relation of the burner and Specication of Letters Patent.

Patented Sept. 9, 1919.

Serial No. 284,946.

burner head when the burner head is lowered to igniting position, and for automatically procuring rc'engagement of the burner head and drum when the head is raised to its proper burning position. Thus, when th-e burner head is lighted, open liames occur until the burner head is raised from igniting to burning position to close the space between the head and the drum, and the occurrence of such open flames would thus practically compel the operator to raise the burner head.

A further object resides in the provision of an arrangement for insuring proper seating engagement 0f the burner drum on the burner head trough, whereby mutilation of the capillary burner member is prevented.

AV still further object resides in the provision of an improved mounting for the burner drum wherein a support is afforded therefor additional to the normal support afforded by the burner head trough.

With the above and other objects and advantages in view, which will be app-arent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts, as will be hereinafter more particularly described and defined by the appended claims.

In the accoi'npanying drawings:

Figure l is a view, partly in side elevation and partly in vertical section, of a burner unit embodying my invention.

l Fig. 2 is a similar view, looking toward the back of the burner.

Referring now more particularly bo the accompanying drawings, there is shown a burner drum of conventional nature comprising the outer cylindrical wall 5 and concentric foraminous inner walls 6 and 7 adapted to seat on the burner head and to receive the annular capillary member 8 therebetween, this "capillary member being formed of the usual non-combustible material and seating in the burner head trough 9, the upper portions of the walls of the trough being offset to form seating shoulders 10 for the drum walls 6 and 7, and it is noted that the olset ortons of the trough walls are inclined wiiereby to guide the burner walls to proper seating position as the, burner drum is lowered. The burner trough A1s su plied with oil and is sup orteil b a de pen ing stem 11 which is te escopica l` slidable in a supply pipe branch 12 upstan ing from the main supply pipe 13, which as is coinmon in stoves of this` character, extends horizontally throughout the stove and is fed from a suitable constant level reservoir, the level of oil thus supplied to the burner head being indicated b v the line Y-Y of Figs. 1 und 2. The usual packingr gland 14 is provided at the juncture of the stem and supply branch, the cap of said gland having a wrench l5 associated therewith whereby it may be tightened from time to time.

As in the aforementioned patent, the meclntnisni for raising and lowering the burner head te control the feed of oil through the capillary annulus includes a bracket formed of a single pla-te of metal intermediatcly bent to forni a horif/iontall)l extending' arm 1G through which thc branch pipe l2 is passed, and a vertically extend ing arin 17 having' its lower portion bent to also receive thc branch pipe .l2 und to seni on the attaching bead 1S of said branch pipe, the extremityT of thc arm 17 beingconti-[nml below the main supply pipe i3. A strip l1) is secured to this lowcr extrcniitv ot' the arin 17 b y a bolt 20, and said strip is also secured by a bolt 21 to the arin adjacent its bend whereby to firmly clamp the arm against the main supply pipe and prevent looseness of arts. The horizontal arm 1G of the bracket is also held against looseness by an arched plateQ tensioned by a bolt Q4 passed therethrough and throughthe arm, one end of Said plate engaging the uncture of the arni and the branch pipe. he outer portion of the horizontal bracket arm l is supported by a brace rod 25 haring its lower end mounted on the bolt Z0 and havingv its npper cnd mounted on a bolt 2.6 passed through the dowirturned outer end of the bracket arm -and through a dial plate 27 which is thus secured to the bracket arm. An exceed- .ingly stro g bracket structure is thus provided having all of its parts firmly held against looseness.

The downwardly turned portion of the horizontal bracket arm 16 forms a journal forlthe forward end of an operating shaft 28 which has a secondvjournal in the upper Jor'tion of the vertical bracket arm 17, and immediately rearwardly of this bracket arm theshaft is flattened for rigid securelncnt to one endportion of the crank arm 297 said end `or-tlonY havin its extremity bent inward yrat. 30 where vte form a stop engage- .able with the bracket to limit swinging movementof' thev crank arrn, the crank arm belng shown m Yi'ntermedntte posltion 1n All'link lhas its lower end pivoted to the other end. ofthe crank arm and has its upper' end nwardyoifset and 'ivoted at A352 tothe burner 'head trough 9 a jacent its iuncture .with the stem 1'1.

Thuis rotationdf thejfshsft 28 will raise andiower the burnerhead, andl thisrctaf burner head,

ot' the burner drum and burner head when the bead is lowered to igniting position, and at the saine time to provide additional support and centeringnieans for the burner drinn1 a vertical rod 34 is provided concentrically of the burnerhead and drinn, said rod having` its lower end o'lff-set and secured at 35 to the back of the vertical bracket nrm 17. This rod is passed through n sleeve 2G carried by :md depending' from a 'loraininous plaie 23T ctcndinoacross lho upper por lion oi tlul burner uoad. und thc upper cud ot the rod is cnpjagcd in a socket sleeve 3S carried b v a l'ornminious plate Il!! carried by the lower portion of the inner drinn wall (l. The rod extends to such height as to engage the end of the socket sleeve at the normal limit of downward inovcnient of the burner head and drinn in burning; position. Hence, as the burner head moves farther downward to ignitingposition, the burner drum will be held against movement and thus the de-- sired spaced relation of the head and drum will be procured to permit the insertion of a match therebetween for lighting' the burner head. As heretofore stated, it has been heretofore customary to raise and lower the drinn manually in lighting' the burner and practice has demonstrated a liability of the operator to neglect to raise the burner head from lighting to burning position, thus resulting in a smoky and unsatisfactory operation. The present arrangement, in addition to increasing the convenience of opera tion of the stove, practically insures a proper operation since the occurrence of reeflames between the burner head and drum `after lighting would make such active impression u on'the mind of'theop'erator as7 to insuret e raising of the burner hea'id from lighting position andconsequently house'thc flames within the burner drum. The rodf 34, by its engagement in* the sleeve 36 of the also holds the burner head against tilting `movement on the stem 8. The rod further Servesfto facilitate proper seating of the burner drum'fin a centered position, by its engagement with the central portion of the drum, to prevent possible mutilation of the capillary member of the burnerhead, which becomes sornewihatibrittleupon continuous use.

'WhilelI have shown andi described a preferred embodiment ofmy invention,I it ywill be aplgirreciated"`= that various changes-and inodlioatcnr *et structure may' be employed within the scope of the appended claims, without departmg in any manner from the spirit of my invention.
